CURTAIN-FIXTURE.

SPECIFICATION forming part of Letters Patent No. 358,377, dated February22, 1887. Application filed May 10, 1886. Serial No. 201,722. (Nomodel.)

To all whom it may concern..-

Be it known that I, THOMAS M. BRINTNALL, a citizen of the UnitedStates,residing at Maryville, in the county of Nodaway and State ofMissouri, have invented certain new and useful Improvements inCurtain-Fixtures; and I hereby declare the following to bea full, clear,and exact description of the same.

My invention relates to a particular form of clamp to serve in attachingcurtains upon the poles on which they are commonly hung, or shades upontheir rollers, securely but in a manner sufficiently yielding to preventinjury, by tearing, to the curtains or shades if subjected to unduestrain. v

It is my object to provide a clamp for the above-named purpose whichshall present the advantage of use stated, and also permit of its readyadjustment or detachment in hanging or taking down curtains or shades.

To this end my invention consists in the general construction ofmyimproved device; and it also consists in certain details ofconstruction and combinations of parts, all as hereinafter more fullyset forth.

In the drawings, Figure 1 shows the upper part of a window, in frontelevation, with a,

shade-roller in position provided with my improved clamping device; Fig.2, an end view 'of the same, and Fig. 3a perspective-view of two clamps,several being for use in clamping a single curtain.

The-device comprises springy metal, preferably wire, bent to form loopsA, each composed of transverse curved strands r and r, connected by alongitudinal strand,q. The efficiency of the device inits purposedepends upon its form,(clearly illustrated inFig. 3,) and the latter is,therefore, the form of clamp constituting my improvement, a constructioninvolving single or disconnected clamps or loops A having hitherto beenemployed in a somewhat similar form as a curtain-fixture for securingthe weight-stick to the bottom of a tic material in the form of ringscut on one side and clamped into grooves around the curtain-roller.

The connection of the loops to afford a series forming the clamp B isaccomplished in the bending of the wire to produce a longi tudinalconnecting-strand, q, between each pair of loops A, which strands q thusalternate with the strands q, the two being on opposite sides of thedevice. The first curved strand,r,and last one,r, of each device is benton blunted at its extremity, preferably in the form of an eye, 12, toavoid raw ends or sharp points at the ends of the wire, which would tendto tear or otherwise injure the clamped article.

The longitudinal strands q and q, though shown to be straight, may beslightly curved outwardly in form, if desired, to increase the extent ofsurface inclosed by the outlines of the loops and enhance the degree oftheir s'pringy quality in a direction longitudinal of the device.

To use the device, which, besides its useful function, affords anattractive ornament, the curtain or shade is applied to the supportingpole or roller, (a sufficient width at the end upon which the article ishung being applied,) preferably to cover about one-half of thecircumference of the pole or roller.

The clamps B are made in different sizes to fit upon poles or rollers ofdifferent diameters,

and should,by preference, extend more than half-way around.

The application or adjustment of the clamp Bis performed by springing itupon the applied end of the curtain or shade over the pole or roller,the length of which determines the number of connected series of loops Aemployed, and the number of loops in each series may be varied accordingto the size of wire used, a clamp of comparatively fine wire requiring agreater number of loops A and closer together than one of heavier wire.

The device thus formed of loops in connected series possesses theadvantage of dis tributing and equalizing the sustaining-pressure andcompensating in itself, from one part to another, for any irregularityin the curtain or shade at the part where it is sustained.

The detachment of the clamps is accomplished as readily as theiradjustment by simply pulling them off.

What I claim as new, and desire to secure by Letters Patent, is

1. A curtain-clamp comprising a series of loops, A, formed of acontinuous length of springy material bent to produce curved strands 1'and a", longitudinal strands q, and longitudinal strands q, connectingthe loops, substantially as and for the purpose set forth.

2. A curtain-clamp comprising a series of loops, A, formed of acontinuous length of wire bent to produce curved strands 1 and 1",longitudinal strands q, longitudinal strands q, connecting the loops andblunt ends 19 at the extremities of the clamp, substantially as and forthe purpose set forth.

3. A curtain-clamp comprising a series of loops, A, formed of acontinuous length of wire bent to produce strands 1- and 9-, curved toform each more than one-half a circle, longitudinal strands q, andlongitudinal strands 2o qconuecting the loops, substantially as and forthe purpose set forth.
